Looking for the color schemes for the wiring to the instrument guages for Mercruiser. Mine got pulled off when installed radio and not sure what color goes where as my wire colors don't match the book colors on in the Mercruiser/Stern drive 1961-1992 Seloc Repair manual I have.<br />Any one have Grey, Tan and purple wire in their wiring harness, where do they go?<br /><br />If I direct wire the starter from the ignition key what wire goes where?

Re: Guage wiring

Tan goes to your water temp sender terminal on the gauge.<br /><br />Gray goes to the tachometer "S" terminal.<br /><br />Purple is the switched "hot" ignition lead that goes to the "B+" or "I" terminal on your gauges.
